2 Claims.

1 This invention relates to disinfectors and more particularly to the method and means for applying measured quantities of liquid disinfectants drop by drop, to the surface of standing water in toilet bowls and the like.

With the above function in view, among the objects of the invention is the provision of a self contained hermetically sealed container for liquid disinfectants that may be unsealed and installed with the minimum of effort by the user.

Another object is the adaptation of the invention for use in mosquito abatement districts for automatically applying oily iilms to pools of stagnant water.

Water standing in toilet bowls, urinals and other toilet facilities becomes contaminated and contributes to the spread of disease by ying and crawling insects using it as a thirst quencher.

'The same is true of stagnant water in the open,

where mosquitoes and other disease spreading life propagate. These dangers to life and health can be eliminated by a thin lm of disinfectant floating on the surface of the water. In human habitations incidental bad odors can be neutralized by appropriate deodorants added to the disinfectant.

An advantage of the present invention is its simplicity and low cost of production. No sep-- arate container for the disinfectant is required because the Whole apparatus can be discarded and replaced more cheaply and easily than to provide refills. However this is provided for in the larger units Where a considerable number of sanitary units are served by a common disinfector.

When emptied the disinfector assembly is cheap enough to be discarded, if fabricated from relatively inexpensive plastics.

In this specification and the accompanying drawings the invention is disclosed in its preferred form. But it is to be understood that it is not limited to this form because it may be embodied in modications within the spirit of the invention, as defined in the claims following the description.

In the one sheet of drawings:

Fig. l is a vertical section of a. disinfector constructed and installed in accordance with this invention.

Fig. 2 is a plan View of the same from below.

Fig. 3 is a modified form adaptable to the larger units permitting the refilling of the reservoir and for outdoor use. Y

Fig. 4 is a View similar to Fig. 2, showing a modied form of mounting clamp.

In detail the construction illustrated in the drawings, referring rst to Fig. 1, comprises the base I, having the annular ange 2, and the nipple 3, preferably formed integrally therewith.

Diametrically opposite the nipple, the segmental socket 4 is formed in the bottom of the'base. The cylindrical head 5 of the clamp ts snugly into the socket 4 and hasthe radial jaws 6, 1 protruding therefrom into opposed relation to the nipple 3 to form therewith a three jawed resilient clamp projecting below the base, I.

The nipple 3 extends downwardly into the overow pipe X, andthe jaws 6 and 'I engage its outer periphery to securely hold the base I above the top of this pipe. The lower edges of the jaws are formedl at an angle to the horizontal plane of the base to insure the correct positioning of the base on the overflow pipe, by preventing its application in any other manner.

The tube 8 extends through and is cemented into the nipple 3 and projects above and below the base I. The lower end of this tube is hermetically sealed by dipping it in a solvent and pinching the end of the tube, as at 8'.

The wick 9, preferably composed of a length of absorbent paper, such as filter paper or paper towel stock, extends the full length of the tube 8, protruding above its upper end and is bent back so that its end approximates contact with the top of the base I.

The upper end of the tube 8 and the protruding wick portion are enclosed within the cylindrical cap I0, the open end of which contacts the top of the base surrounding the tube. The lower o end of this cap has a small notch therein at II,

adjacent the protruding end of the wick.

The reservoir cup I2 has its open end iitted snugly around the periphery of the base I abutting the ange 2 and is hermetically sealed thereto by an interposed solvent or cement. The top I3 of the cup I2 bears against the top of the cap I0 and forces it against the top surface of the base.

Before assembling the reservoir cup I2, it is filled with the desired disinfectant D. The base I is then inverted and inserted into the open end of the cup and sealed thereto. The assembly is then packed in a suitable container ready for marketing.

The invention operates substantially as follows: The disinfector is held upside down and the lower end of the tube 3 is snipped off with scissors or a knife, and inserted within the overflow pipe X until the clamp formed by the nipple 3 and the jaws 6, 'I engage the upper periphery of the pipe, as described.

In this position the upper protruding end of the wick, saturated with the disinfectant D entering the notch Il, begins to function, dnawing the disinfectant out of the reservoir I2 and spilling it drop by drop down the overflow pipe from the lower, severed end of the tube 8.

The overow pipe X is the conventional toilet tank assembly, and discharges directly into the toilet bowl, on top of the residual water supplied to the bowl by the auxiliary supply pipe Z, after the tank iiushing is completed.

In mosquito abatement districts where it is desired to coat the surface of stagnant Water with medicaments, a supporting stake I4 can.. beinserted into the socket 4 andthrust into the bottom of the pool or streams feeding into the pool, see Fig. 3.

In the larger units and permanent installations, a filler cap I5 such as shown in Fig. 3 can be provided for refillingY the reservoir I2.

The ow of disinfectant can be increased by increasing the size or capacity of the wick 9 or the notch II. Another alternative for increasing the iiow of heavyviscous oils, would vbe to provide a small vent hole suchas I0 through the upper portion of. the cap I0 to break the airlock above the liquid in thereservoir I2.

The modiedV formof. clamp shown in Fig. 4 consists of two projecting pins 6x, 1x, in opposed relation to the nipple 3V and adapted to engage the periphery of the pipe X in a manner similar to the jaws 6, 1. TheV design. of. the invention is susceptible to modifications to. meet the type of plastics used and manner of molding, injecting or otherwise forming the base I, and other parts of the assembly.' For instance the base I, clamp 3-6-1 and tube 8, may be formed integrally. The cap I0 andreservoir I2 may besimilarly formed in one piece.

Having thus described this invention, what is claimed and desired to secure by Letters Patent is:

1. A disinfector comprising a closed reservoir containing a fluid and having a nipple extending below the base of said reservoir; a, pair of jaws on said base in juxtaposition to said nipple and cooperating therewith to form a clamp for mounting said base on: the end of a pipe into which said nipple is extended; a tube having one of its ends sealed and its open end portion extending through said nipple and terminating near the top of said reservoir; 4and a wick eX- tending upwardly in said reservoir and downwardly within said tube.

2. A disinfector comprising a closed reservoir containing e, iluid and having a nipple extending below the base ofsaid reservoir; means on said base in juxtaposition to said nipple and cooperating therewith to form a clamp for mounting said blase on the end of a pipe into which said nipple is extended; a tube having oneof itsends sealed and its open end portion extending through said nipple and terminating ynear the top of said reservoir; and a.wicky extending upwardly in slaidreservoir and downwardly within said tube.
